Infants at the age when SIDS occurs quite frequently spend most of their sleep in a stage known as rapid eye movement or REM sleep. This sleep stage is characterized by the dysregulation of various mechanosensory airway and chemosensory autonomous reflexes that are critical for survival (18, 19).
Some babies sleep longer when positioned on their stomachs, but remember that deep sleep can put a baby at a greater risk of SIDS when startling reflexes are subdued. “This may be why breastfeeding and pacifier use has been shown to decrease SIDS,” explains Dr.
Results The majority of SIDS deaths (83%) occurred during night-time sleep, although this was often after midnight and at least four SIDS deaths occurred during every hour of the day.
The peak incidence of SIDS occurs between 1 – 4 months of age; 90% of cases occur before 6 months of age. Babies continue to be at risk for SIDS up to 12 months.
We found that even normal infants seem to be born with an ability to awaken in response to low oxygen, but they lose this at ~2-3 months of age, which is when the incidence of SIDS peaks.
While the cause of SIDS is unknown, many clinicians and researchers believe that SIDS is associated with problems in the ability of the baby to arouse from sleep, to detect low levels of oxygen, or a buildup of carbon dioxide in the blood. When babies sleep face down, they may re-breathe exhaled carbon dioxide.
Infants (children under 1 year) had the highest rate of death in all jurisdictions in 2020, accounting for 59% of all child deaths in Australia. Rates of infant deaths from Sudden Infant Death Syndrome (SIDS) and undetermined causes ranged between 0.16 and 0.52 per 1,000 live births.
White noise may also block out excess stimulation and thus, reduce stress levels in babies. But older claims that white noise can reduce the risk of SIDS need more current research.
The potential factors that contribute to the occurrence of SIDS include inadequate prenatal care, low birth weight (<2499gr), premature infants, intrauterine growth delay, short interval between pregnancies and maternal substance use (tobacco, alcohol, opiates).
SIDS has no symptoms or warning signs. Babies who die of SIDS seem healthy before being put to bed. They show no signs of struggle and are often found in the same position as when they were placed in the bed.

Sleep your baby on their back. Keep your baby's head and face uncovered. Keep your baby's environment smoke free, before and after birth. Make sure they have a safe sleeping environment.
Our data show that infants who were less awake and less difficult to settle than usual, which could result in them being less responsive than usual to external stimuli, were at greater risk of SIDS.
In post-mortem investigations, evidence of suffocation is not found in most babies who die of SIDS. SIDS may be associated with the brain's ability to control breathing and arousal from sleep, low birth weight or respiratory infection.
During wintry months, you may be tempted to wrap your baby in extra blankets and warm clothes before sleep. But take care. Over-bundling may cause infants to overheat, increasing their risk for sudden infant death syndrome (SIDS)—the third leading cause of infant death.
Babies who share a bed with other children or adults. Mothers who smoke during pregnancy (three times more likely to have a baby die of SIDS) Exposure to passive smoke from smoking by mothers, fathers, and others in the household (doubles a baby's risk of SIDS)
Babies and parents who room share seem to sleep less soundly. If babies wake up more easily, this may reduce the risk of SIDS. Additionally, room sharing infants are more likely to breast feed more frequently (which has also been shown to reduce this risk of SIDS).
A pacifier also keeps the tongue forward in the mouth, so it can't block the airway. The American Academy of Pediatrics (AAP) does recommend parents give pacifiers at naps and bedtime because they can help protect against SIDS.
Babies who are breastfed or are fed expressed breastmilk are at lower risk for SIDS compared with babies who were never fed breastmilk. According to research, the longer you exclusively breastfeed your baby (meaning not supplementing with formula or solid food), the lower his or her risk of SIDS.
An immobilized infant can't crawl into dangerous asphyxiating environments. Also, swaddling prevents infants from pulling bedding over their heads. Both are risk factors for accidental suffocation and/or SIDS.
If you keep white noise at a safe level and at a safe distance from your baby's ears, there's absolutely nothing to worry about. Of course, it should go without saying that you not blast your white noise machine at max volume right next to your little one's head all night long.
The 'arms up' behavior observed in babies is closely related to the Moro reflex, also known as the startle reflex. This involuntary response is part of a baby's developing nervous system and serves as a protective mechanism.
Here are the statistics on SIDS and SUID based on information gathered from the CDC's Division of Reproductive Health's monitoring programs: About 3,400 babies in the United States die suddenly and unexpectedly each year. About 1 in 1,000 babies die from SIDS every year.
The highest SIDS rates in 1990 (>2.0/1000 live births) were in Ireland, New Zealand, and Scotland. More recently, the highest SIDS rates (>0.5/1000 live births) are in New Zealand and the United States. The lowest rates (<0.2/1000) are in Japan and the Netherlands.
The incidence of SIDS has been more than halved in recent years due to public health campaigns addressing the known major risk factors of prone sleeping, maternal smoking and overheating.
